Alveolar Bone: Alveolar bone surrounds the tooth to a level approximately 1mm apical to the CEJ. This part of the alveolar bone that covers the alveolus is referred to as lamina dura, a cortical bone. The alveolar bone is constantly renewed in response to functional demands with the help of bone-forming Osteoblasts and Osteoclasts. The Osteoblasts produce Osteoid, consisting of collagen fibres and a matrix that contain mainly proteoglycans and glycoproteins. The bone is covered with the Periosteum, which functions as an osteogenic zone throughout life. The alveolar bone further consists of two components, the alveolar bone proper and the alveolar process.
